>>10116452This is an immersion circulator.
It allows for the hands-off cooking of meat and other foods over the course of, say, a reading session or the evening the day prior.
Goods that have been cooked this way retain their juices and flavours and can be put into the fridge in pre-portioned units to be seared off for a total of 10 minutes at most in order to cut down on kitchen waste and hassle whenever fresh food is needed.
This works especially well for fowl (use family sized low-priced chicken breast, season liberally, cook sous vide, refrigerate in glass or BPA free plastic, have food for at least a week) though where it shines the brightest is the preparation of absolutely legendary steaks.
In essence, it's how you create large amounts of pan-ready TV dinners with minimal time investment and a much lower price point, not to mention higher quality.
An immersion circulator goes for about 60-100 bucks and brings in the cost within roughly three weeks to five months, depending on how much pre-prepared food you ate before that.
